Amcor shares lift on sales growth
Amcor shares are outperforming today, up 4.5% at $55.05 apiece.
This follows the release of the global packaging giant's March quarter results (Q3 FY 2026).
The ASX 200 stock said it realised acquisition synergies of US$77 million during the quarter, now that its acquisition of Berry Global is complete.
"Third quarter results were in line with expectations and reflect the resilience of our business as we mark the first anniversary of bringing legacy Amcor and Berry together as One Amcor," CEO Peter Konieczny said.
Highlights from the quarter included a 77% year-on-year increase in net sales to US$5.91 billion.
And adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA) of US$892 million were up 87% from Q3 FY 2025.
On the passive income front, the company, which pays quarterly dividends, delivered a record payout of 91 Aussie cents per Amcor share, unfranked.
Light & Wonder shares sink on Q1 update
Unlike Amcor shares, Light & Wonder shares are taking a beating today.
Shares in the ASX 200 gaming company are down 8.9% at the time of writing, changing hands for $102.04 apiece.
Investors are favouring their sell buttons following the release of Light & Wonder's first-quarter results (Q1 2026).
On the positive side of the ledger, quarterly revenue of US$790 million was up 2% year on year. And adjusted EBITDA of US$327 million was up 5%.
However, statutory net income of US$52 million was down 37% from Q1 2025. Management pointed to some US$50 million in provisions tied to past legal matters for much of that decline.
Tabcorp shares crash on AUSTRAC investigation
Joining Light & Wonder and Amcor shares in making waves today, Tabcorp is grabbing attention for all the wrong reasons.
Shares in the ASX 200 gambling company are down a sharp 20.7% at the time of writing, trading for 91.2 cents apiece.
In a market release this morning, Tabcorp reported that AUSTRAC has "a number of serious concerns" regarding the company's ability to effectively identify, mitigate, and manage its money laundering and terrorism financing risks.
AUSTRAC has now commenced an enforcement investigation.
Commenting on the investigation that's hammering Tabcorp shares today, CEO Gillon McLachlan said:
I am committed to leading a compliant and safe company that understands its risk obligations. Uplifting our risk capability has been an ongoing part of the company's transformation and we will work constructively with AUSTRAC through this process.
